IMPROVEMENT IN CQOKlNG-STOVES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, LEMUEL DUNHAM, of LincolnCentre, in the county of Penobscot and State of Maine, have invented anew and improved Gombined Heating and Cook-Stove; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being bad to the accompanying drawing forming part ofthis specification.

This invention relates to improvements in stoves; and

It consists in a cooking attachment to what is known as the Franklinheating-stoves, as hereinafter described. 1

Similar letters of reference indicate corresponding parts. Y

I propose to attach to the back and top of a Frank-- lin heating-stoveA, or other stove of the same general character, of any approvedpattern, a cooking apparatus, consisting of a case, B, similar to thatpart of an ordinary cooking-stove above the fire-place containing theoven, up which I conduct the heat by a flue, O; and I also place) anoven, D, in it, and the ordinary pot-holes, with removable cross-bar atthe top; also the stovepipe connection E, for conducting away thevproducts of combustion.

And for the purpose of applying the heat more directly to the cookingattachment than would be the case if the fire was made when cooking atthe bottom of the stove A, in the usual place, I arrange the grate F sothat it can be readily taken from its position at the-bottom, and placedon supports G, just below the lower edge of the front plate H ofstove'A, and at one end of the latter above the grate-I'- provide adoor, I, for introducing the fuel above the grate,

To enable me to arrange the grate at this place, I arrange the backplate J, which -in the ordinary Franklin stove pitches forward to throwout the heat, so that it may turned backward parallel with the verticalwall of the back plate of the stove.

This back plate is in this instance held in either position by thesliding plate K, lying upon the bot, tom plate of flue C, and having agroove L in the under side, near the front edge, in which the upper edgeof the back plate bears.

The friction ofthe plate K on the flue bottom will hold, the back platein any position.

I propose to arrange a damper, N, on the top of the oven, to close oneof the side vertical passages, so as to cause the heat to rise up alongthe ends more that it otherwise would.

By this simple arrangement I am enabled not only to utilize the stove Afor cooking purposes, but I also very greatly-increase the efliciency ofthe same for heating purposes, for the cooking attachment adds greatlyto the radiating surface.

In connection with this cooking attachment the paltAmay have pot-holesand a removable crossbar at the top, whereby it may also be, inconsequence of the grate being placed so near it, equally asfserviceablefor cooking as the corresponding part of an ordinary cook-stove.

The advantages of my improved stove in families which require a combinedheating and cook-stove will be readily appreciated from the foregoingdescription.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- I 1. The pipeconnection E, chamber B, and fine 0, combined as described, with, andarranged above, the adjnstably-grated Franklin stove A, for the purposespecified. p

2. The end-grooved plate K, movable on the horizontal bottom of flue O,to adjust. the back wall J, and hold it by friction in any position, asdescribed.
